Study Reveals 'Additive Advice Bias' in Mental Health Support, Including AI Chatbots

The 'Additive Advice Bias' in Mental Health Support

A groundbreaking study conducted by researchers from the University of Bath and the University of Hong Kong has uncovered a pervasive bias in mental health advice. The research, published in Communications Psychology, reveals that most mental health recommendations tend to add tasks to people's lives rather than suggesting the removal of harmful activities 1

The Nature of the Bias

The study, comprising eight separate investigations with hundreds of participants, found that this "additive advice bias" is prevalent across various contexts. Whether it's advice shared between individuals, posts on social media platforms, or even recommendations from AI chatbots, the tendency is to suggest additional activities rather than advocating for the cessation of detrimental habits 1

Key findings from the research include:

1. Dominance of Additive Advice: In all scenarios studied, people were far more likely to suggest adding new activities rather than removing harmful ones 2

2. Perceived Ease and Benefit: Participants viewed doing more as both easier and more beneficial compared to eliminating harmful behaviors 1

Dr. Tom Barry, the senior author from the University of Bath, emphasized the potential drawbacks of this bias. He stated, "In theory, good advice should balance doing more with doing less. But we found a consistent tilt towards piling more onto people's plates and even AI has learned to do it. While well-meaning, it can unintentionally make mental health feel like an endless list of chores" 1

The Role of AI in Mental Health Advice

As AI chatbots increasingly become a primary source of mental health guidance, there's a risk of amplifying this bias. Dr. Nadia Adelina, co-author from the University of Hong Kong, suggested a potential solution: "Building in prompts to explore what people might remove from their lives could make advice more balanced and less overwhelming" 2
